Performance Sleep specializes in high quality electric adjustable beds. The mattress size you would most typically find with a motorized bed would be a Twin XL or Queen. Twin XL (long twin), is a twin mattress with the length of a queen or king. This is an important distinction as with adjustable beds, the higher you raise the head and foot, the shorter the bed effectively becomes.

Other than Twin XL and Queen, many adjustable beds are offered in many of the other common sizes including Twin/Single, Double/Full and California King. Performance Sleep is capable of sourcing any of these sizes. Our authorized retailers are the best resource for mattresses in these sizes.

Bigger is Better

Your mattress size is very important. Bigger really is better when it comes to the appropriate mattress size. This is especially true when sharing your bed with a partner. A larger mattress simply ensures less sleep disruption by keeping sleepers further apart and by distributing movement amongst a more generous surface area.
